DaveM's website: : https://www.partsnotincluded.com/diy-stream-deck-mini-macro-keyboard/

Since the version of DaveM's DIY Stream Deck only had 8 buttons i decided to create my own version. I than found the version with 12 Keys from CDante.
The code is nearly the same and can be found in the commentsection of CDante and DaveM (just add some extra F keys to the pins)

I didnt do the wireing like the version of Dante, but its nearly the same. just look at the pictures: https://cdn.thingiverse.com/assets/f9/7b/49/7d/7d/20200225_163030.jpg
all switches need to be connected to the ground wire which than can be soldered to the ground pin on the Arduino micro Pro 5v ATmega32U4 5V
